Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I recently installed this ECM on my 2018 Chevrolet Suburban, and I couldn’t be happier with how smoothly everything went. The fact that it came VIN programmed saved me so much time, and the plug-and-play design made the swap straightforward—even for someone like me who isn’t a professional mechanic. Shipping was surprisingly fast, arriving well within the expected timeframe, which was a relief. After installation, the truck fired right up with no hiccups, and it runs just like it did from the factory. Overall, this was a hassle-free experience that got my Suburban back on the road in no time.
